Plastic, composed of synthetic or natural polymer chains, has become indispensable in daily life and industrial manufacturing due to its low cost and high malleability, particularly in medical products. With technological advancements, plastic processing techniques have evolved rapidly, bringing unprecedented changes to the molding of plastic parts for appliances, medical devices, and other industries. Today, let's delve into Dongguan Yize Mold Co., Ltd., to gain insights into its core injection molding processes for medical components.

1. Precision Injection Molding: The Pursuit of Extreme Accuracy in Size and Weight

Precision injection molding is renowned for its high-precision control over the size and weight of products. Thanks to high-pressure, high-speed injection molding machines and advanced open-loop or closed-loop control systems, precise regulation of injection parameters is achieved. This technique demands extremely accurate molds, and Yize Mold, with its profound experience in mold design and manufacturing, has successfully applied it to the production of small and medium-sized precision medical components, ensuring exceptional quality for each product.

2. Rapid Prototyping: Flexible Production Without Molds

Rapid prototyping technology breaks the traditional mold constraints, enabling small-batch and quick production of plastic parts. Among them, laser scanning prototyping stands out for its efficiency and flexibility. Yize Mold utilizes laser scanning equipment to transform computer-designed 3D models into physical objects, layer by layer, with precise shaping, providing great convenience for the research and development, as well as prototyping, of medical products.

3. Melt-Core Injection Molding: The Art of Cavity Creation

Melt-core injection molding is tailored for medical components requiring extremely high cavity roughness and precision. Yize Mold employs a unique process of first molding the core, then using it as an insert for injection molding, and finally allowing the core to melt and flow out, precisely shaping complex cavity structures. The precise control of the melting points of the core material and the plastic part is crucial to the success of this technique, demonstrating Yize's profound expertise in the integration of materials science and injection molding processes.

4. Gas/Water-Assisted Injection Molding: Energy-Efficient and Excellent Quality

Gas/water-assisted injection molding is widely used in the production of medical injection-molded parts, characterized by material savings, minimal shrinkage, good appearance, and high rigidity. Yize Mold injects gas or hot water into the mold cavity almost simultaneously with the plastic melt, forming a sandwich structure. After the plastic part is shaped, the gas or water is released, and the mold can be ejected. Despite the ongoing development of domestic equipment, Yize has accumulated rich application experience to ensure the stable implementation of each technology.

5. Electromagnetic Dynamic Injection Molding: Micro-Plasticization and Reduced Internal Stress

Electromagnetic dynamic injection molding technology utilizes electromagnetic force to drive the screw to vibrate axially, achieving micro-plasticization of the plastic and resulting in a denser structure and reduced internal stress in the plastic part during the holding phase. This technique places higher demands on mold design and manufacturing, but Yize Mold, with its deep foundation in the mold industry, has successfully applied it to the production of medical injection-molded parts, further enhancing product quality and reliability.

Conclusion:

Since its establishment in 2007, Dongguan Yize Mold Co., Ltd. has been dedicated to precision mold design and manufacturing, as well as the production of precision injection-molded products, particularly in the fields of automotive connectors, medical product injection molding, cleanroom injection molding, and PFA custom injection molding. It provides one-stop solutions from product design to after-sales service. Looking ahead, Yize will continue to explore and innovate, leveraging more advanced injection molding processes to contribute high-quality, high-precision plastic products to the medical industry and drive the continuous progress of medical technology.
